Too many?

Ok, I have a 20 gallon planted tank. 6 Green tiger barbs, 4 regular tiger barbs. I have two HOB filters. One rated for a 30 gallon, the other for 15 (Used when firing up the QT tank). I would like to put some Corys in there. I have shelter and a small cave dug out that I think they would find rather nice. Now I know corys like friends so I couldn't just get one or two, which means I'm probably starting to over fill this tank. Am I asking too much? If so, is there another bottom dweller I should look into?

The the calculator (adadvisor) in my signature to determine if the filters and tank will work with your stocking idea.

Thanks.
With what I want I'm looking at 128% filtration with 108% tank capacity. So as long as I keep my filtration up I should be good.

Your regular Tiger Barbs are too big for that tank. They also can be very territorial(leading to aggression) toward other species especially in a small tank like that. Lastly, Tigers are best kept in large schools which cannot be done in that size tank.

I agree with the above. Tigers are very nippy in lower numbers and will thrive in tanks of 40 gallon+

Can you get a bigger tank?

I have a 30 gallon and considered TBs when I was looking at stocking, but felt they needed more room than I could realistically provide.

Hmmmm... well that is problematic. Right now I have no other tank I could get. I have only the four regular tiger barbs and everything I read said they would school just fine with the green tigers. If I forgot the cory's and just left it as barbs would they manage?
